Scrap the bell reducer. And I was wrong about the chamber, disregard what is written below.

It reads: 7200 2" Type 1 SCH 40 ASTM D-2665 NSF-dwv PVC 1120 PR 280 PSI @ 23c ASTM D-1785

Sch 40 is just the wall thickness. That means pretty much nothing. What you need to see is SCH 40 NSF-PW, Not DWV

It says pr 280psi idiot. Therefore it is ok to use don't listen to blind.

You can tell how awesome a cannon is by the pressure used.

God Damn People, Sch 40 is just a wall thickness. Read all the writing in red on your air chamber.

ok, so if the chamber was was 1mm thick and it says it can go to 250psi do u think it's true!!!

i think it's better to have a thicker wall and have it say 200psi then a thin wall saying 500psi
